IMPROVEMNT IN LUBFICATING PULLEVS.

Specification forming part of Letters Patent No. 143,830, dated October21,1873; application tiled August 1, 1873.

To all whomz't may concern:

Be it known that I, J. KING MCLANAHAN, of Hollidaysburg, in the countyof Blair and State of Pennsylvania, have invented a new and ImprovedLubricator, of which the following is a specification:

In the accompanying drawing, Figure l represents a front elevation of arevolving Wheel or pulley, partly in section, on the line c c, Fig. 2,showing arrangement of lubricating part, and Fig. 2 is a verticaltransverse section on the line m m, Fig. l.

Similar letters of reference indicate corresponding parts.

The object of my invention is to provide a simple and convenientlubricating device for the revolving wheels of pulleys, cars, 85o., bywhich a saving in the consumption of oil and a decrease in the wear ofthe axles are produced.

The invention relates to an improvement in the class of pulley and carWheel lubricators in which a tube is arranged to projectradially fromthe hub Within a chamber, and through which the oil is conducted to theaxle-j ournal, as illustrated in the patent of M. Gr. Ryan, May 9,1871.The invention consists in the combination of a wire-feeder with theoil-conducting tube, as hereinafter described.

In the drawing, Arepresents the wheel, pulley or other revolving body,in which two adjoining spolres or arms, a, are connected, so as to formthe lubricator or oil=box B 5 or the same may be placed aroimd the hub.This oil box B may be either cast with the Wheel A or be made separate,and afterward attached in the usual manner. A tube, b, is either cast orotherwise set into oil-box B, passing through the core of wheel A to theaxle of the same. Afeeder, d, is applied in the box B, either to theinside of tube b or to the tire. The tube b projects above the oil inbox B, and is supplied at each revolution 0i' Wheel or pulley A with asmall portion of oil, which, by by adhering to the feeder d, is thencecarried t-o the journal. rIlle inclined side` aperture e withscrew-stopper c allows the refilling of box B, and regulates also thequantity of oil in the same.

The lubricator is quickly and easily attended to, and reliable andeconomical in operation.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The wire-feeder d in combination with the tube b,connected with the inner periphery of the wheel within the oil-box B, asshown and described, to operate as specified.

, J. KING MCLANAHAN.
